This invention relates to a collapsible umbrella of the kind wherein the stretchers are pivoted to the outer rib sections and supported by auxiliary struts, and the invention consists essentially in connecting the upper ends of the struts to a sleeve which is arranged to slide on the telescopic umbrella stick.

This arrangement has'the advantage that, as the sleeve moves over the stick sections and the catches therefor, a resistance will be oiiered to the sleeve which re-acts by means of the struts on the stretchers so Vas to extend the outer rib sections before the ribs are bent enough to hinder such extension.

This effect is enhanced by making the uppermost stick section larger than the contiguous lower section so that it can act frictionally on the sleeve.

Fig. 1 ot the accompanying drawing represents a side view, partlyin section', of the improved umbrella frame in closed position, only one of the ribs and'its accompanying parts being shown, and Y .Y

Fig. 2 is a sectionalview of the lower part of `the frame in collapsed position.

The umbrella comprises rib sections 1 and 2 which are slidably connected to each othery by means of rings 3 and 4, the sections 1 being pivoted to the crown 5. The stretchers 6 are connected by joints 7 to the rings 401i the outer rib sections 2. The stick is composedof telescopic sections 8, 9, 10 and 11 which are locked by catches 12, 13 and 14 preventing longitudinal relative displacement. Connected to the lower end of the stick section 8 is a tubular handle 17. The latter can, after the catch 12 has been depressed, slide over the runner 18 between the stretchers G and the ribs 2 while the stick section 8 slides over and depresses the catches 13 and 14 so as to allow the upper stick sections to collapse. The runneris locked by the catch 14 with the umbrella frame in open position. Connected to each stretcher by means of a joint 19 is an auxiliary strut 2O which, When the umbrella is opened, supports the stretcher and helps it to extend the outer rib section 2.

In the closed position of thel umbrella frame, the runner 18 is locked by a catch 23 provided, under the runner, with a nose 24- whereby thecatch can be operated for releasing thel runner. On the collapse of the umbrella frame the runner slides over the. nose 24 and moves tothe bottom of the handle,*as 55 -shownin Fig. 2,"afnd Vthe catch 23 remains in Y i by they,on the closing .of the umbrella, en- `gageytliestretchers v(Sand exert'thereon an outward thrust wherebyv the re-opening of the umbrella-is facilitated.

l/Vhile the auxiliary struts 20 are connect- 65 ed at one end, by means of thejoints 19, to-m Athe stretcher 6 the other end is connected to Y a sleeve 27 which slides on the stick. This sleeve Vis. freely slidable. However, since it is connected to the auxiliary struts, it canonly 70 move togetherwith all the latter.,V Thus, on@- the handle 7 being pushed over the stretchers 6, the sleeve and struts co-operate to support the stretchers. The joints 19 ofthe struts 20 arearranged kon the stretchers 6 outside 75 the .position to which the handle can be pushed. Thus the handle is prevented from acting with too great force on the joints 7 so as to hinder the relative sliding movement of the rib sections. The stick section 11 over which the slide 27 passes on the opening of the umbrella is largerthan the contiguouslower section is adapted to resist the movement of the slide, therebyreacting yby means of the'struts on 85 the stretchersG so as to extend the outer rib'N sections 2 before the ribs are bent enough to hinder such extension. o v The runner 18 is adapted to move on to the sleeve27 on the opening of the umbrella. On 90 the closing of the umbrella the sleeve 27 will not be retained by the catch 14 since it moves 1. An umbrella of the character described, 1100 Y,

comprising a stick composed of telescopically connected sections, ribs composed of slidably connected sections, a runner on the stick, stretchers connecting saiol runners with the 5 outerrib sections, a sleeve arranged to slide on the stick, and auxiliary-struts pivoted at one end to said sleeve and at the other end. to the central portions of the stretcliers for supporting the latter in theopen position of the umbrella, said struts being VformedY with knees adapted to bear against and exert out- Ward pressure on the stretehers'wlien the umbrella. is closed. o Y p 2. An umbrella as claimed in claim 1 Wherein the uppermost stick section is larger 4than the `contiguous lower section and'is adapted 13o-offer frictional resistance to the sleeve, substantially Ias and for the purpose set forth. 3. An umbrella as claimed in claim 1 Whe-rein the uppermost stickseotion is larger `-th`an the Aeon-Vtiggguous lower section, a catch on sa-il lower section adapted to retain tbe uppermost section in extended position, said Catch adapted to 'offer friotional resistance to theupWarcl movement of the sleeve on the llatte-r passing theeatch substantially as .and

orthe purpose set forth.
